Description
Correct calcium and magnesium deficiencies before they cost you yield
Plant Magic Magne-Cal+ is a concentrated calcium and magnesium supplement built to prevent and correct the Ca/Mg deficiencies that regularly appear in hydroponics and indoor growing. Calcium and magnesium are essential secondary nutrients for root development, nutrient uptake and cell structure, so when they run short you typically see slow growth, weak stems, yellowing between the veins and disappointing flowering. It is especially useful in coco, hydroponic systems and soft water areas, where Ca and Mg are naturally less available, and it improves the effectiveness of PK boosters through bloom.
Key Benefits
- Readily available calcium and magnesium for balanced, stable plant nutrition
- Prevents and corrects Ca/Mg deficiencies common in coco and hydro
- Stronger roots and improved nutrient uptake throughout the grow
- Healthier leaf structure and stronger stems for better light and load support
- Boosts PK bloom performance, helping support heavier flowering
- Suitable for soil, coco and hydroponic systems
Yellowing between leaf veins, weak stems and poor flowering
Cal/mag deficiency is one of the most common issues indoors, showing as interveinal yellowing, weak stems, slow vegetative growth and poor flower development. Magne-Cal+ supplies these elements in a readily available form, correcting the imbalance and reinforcing cell structure so plants stay resilient and keep filling out through the flowering stage.
How to Use
- Soil, coco and hydroponics: add 0.5-1ml per litre of water as part of your regular feed during the flowering stage
- Deficiency correction: apply at the first signs of Ca/Mg deficiency to restore balance quickly
- Mix thoroughly into the nutrient solution before feeding
- Check EC and pH after adding, and adjust to suit your medium
